The new ExtremEngine 3T picks up where the AeroEngine II Case left off by adding a gigantic 25 CM (250mm) fan to the side panel. The front of the ExtremEngine 3T Case contains the familiar 14CM fan capable of pushing 68 CFM (cubic feet per minute) at a mere 34 dBA while the new side fan adds another 162 CFM at 35 dBA. It's an amazing amount of airflow for such a low amount of noise being generated - and if that isn't enough Aerocool has included a fan controller to tame these beasts.
